The device operates on a supply voltage range of 3 V to 5.5 V, with propagation delays specified at 14 ns for 3.3 V and 9.1 ns for 5 V. Static current consumption is rated at 8 µA. Output drive capabilities include a low-level output current of 32 mA and a high-level output current of -24 mA. The unit supports surface mount installation and functions across a minimum operating temperature of -40°C.

Flip Flops Feature Summary

• Provides edge-triggered data storage via D-type flip-flop architecture with non-inverting polarity
• Integrates tri-state outputs to facilitate direct bus line driving without additional interface circuitry
• Supports configurable operation as either two independent eight-bit units or one sixteen-bit unit

Flip Flops Applications

• System data bus buffer registers
• Parallel I/O expansion ports with multi-output signal latching
• Working registers and temporary data caching
• Switch and router board card bus interface drivers
• Backplane parallel data channels for multi-device bus sharing

Flip Flops Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required SSOP-48 configuration and that RoHS compliance aligns with project requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring wide-bus logic with high-speed performance under standard CMOS voltage levels. The AC series offers a balance of speed and power suitable for general-purpose digital applications. Consider the tri-state capability for shared bus architectures and verify that the SSOP-48 footprint fits the target PCB layout constraints compared to alternative packages like TSSOP or BGA.

Flip Flops FAQ

Can the SN74AC16374DLR be configured as two separate 8-bit registers?

Yes, the chip can be configured as two independent 8-bit flip-flops or operated as a single 16-bit unit.

What is the function of the OE pin regarding the output state?

The buffered output enable pin allows the outputs to be set to normal logic states or a high-impedance state, preventing bus loading when inactive.
